And one American replacing his coffee with NEXUS™ for concentration is Ronin. He used to drink 5 - 6 cups of coffee every day to stay on top of his work load. But now, he only drinks one at most:

"Nexus has been part of my daily routine now for about 6 months and I LOVE IT. I have cut down on my caffeine intake to only a cup a day (I was nearing 5-6 before) and not only do I feel much better, but I'm staying on top of my workload with ease. Thank you, Axon Labs!"
